Approved by:
A4 - 79 D.' E. Whitesell, Chief Date' Component Section I Vendor Inspection Branch Summary Inspection on July 16-19, 1979 (99900004/79-02)
Areas Inspected:
Implementation of 10 CFR 50, Appendix B, including particle attributes, fuel rod manufacture, and action on previous inspection findings.
The inspection involved twenty-eight (28) inspector hours on site by one (1)
NRC inspector.
Results:
In the three (3) areas inspected no apparent deviations or unresolved items were identified in two (2) of the areas. The following two (2) deviations and one (1) unresolved item were identified in the remaining area.
Deviations: Fuel Rod Manufacture - examples where document control was not adequately implemented as required by the QA Manual (See Notice of Deviation, Item A); Fuel Rod Manufacture - a specification requirement on the contamina-tion of gases was not addressed as required by the QA Manual (See Notice of Deviation, Item B).
Unresolved Items:
Fuel Rod Manufacture (Details Section, paragraph D.3.b) 1179 078 060 7910190

Action on Previous Inspection Findings (Closed) Deviation (Report No. 79-01): Design changes were made which did not meet all the requirements established for design control. The desigi changes in question have been included following the established requirements. Currently specification GA 10600 is at revision W, dated June 27, 1979, and no change notices exist at this time.
(Closed) Deviation (Report No. 79-01): The Analytical Chemistry Laboratory procedures were not reviewed properly. Analytical pro-cedures have been issued and are being reviewed by the QA Department.
Procedures, ACD: SA-006 on spetrographic measurements (metal impurties),
ACD:CA-043 on sulfur, and ACD:CA-045 on titanium have been issued.
(Closed) Deviation (Report No. 79-01): The balances in the Analytical Chemistry Laboratory used for metal impurity testing were not calibrated.
The scales in question have been included in the calibration recall system. A survey of the area during the inspection did not identify any additional problems.
(Closed) Deviation (Report No. 79-01):
Procedure QDI 29-2 waived the specification requirement to evaluate the structure of fuel kernels.
The procedure has been revised and structure of fuel kernels is being evaluated currently on a regular basis.
1179 079
3 (Closed) Deviation (Report No. 79-01): The best straight line was not drawn through the calibration points on the test plot of density vs.
gradient position. The procedure QDI 29-5 has been revised to reflect the current practice. The error potential, associated with the cur-rent practice, has been evaluated.
(Closed) Deviation (Report No. 79-01): The acceptance criteria for the weight checks of the reference density balls were not included in procedure QDI 29-5.
The acceptance criteria for the reference density balls has been added to the procedure and the procedure has been imple-mented.
C.
Particle Attributes 1.
Objectives The objectives of this area of the inspection were to verify that:
The inspections made of particle attributes, give assurance a.
that the particles meet specifications and contractural requirements.
b.
The manufacturer's inspection system is capable of detecting cracked, defective, or otherwise unacceptable particles, and reject or otherwise control their utilization.
2.
Method of Accomplishment The preceding objectives were accomplished by:
Review of the Quality Assurance Mancal, dated August 5,1977, a.
Sections 5, 10, 11, and 14, which establishes the general requirements for particle attribute controls.
b.
Review of the HTGR Fuel Specifications, GA 10600, Revision W, which established the specific requirements for particle attribute controls, c.
Review of the procedure QDI-28-31, Sampling Plan and Decision Rules for Inspection of FSV Individual Particle Batches, Revision A. which establishes additional requirements.
d.
Inspection of chemical and physical inspection and testing records of several lots of fuel particles, verification that the sampling plans meet specification requirements, and verification that results were accurately logged, recorded and calculated.

Findings a.
Deviations
- None, b.
Unresolved Items None.
c.
Comments This inspection scoped the sampling plans and reports necessary for lot acceptance. This scope was not covered during the previous inspection.
D.
Fuel Rod Manufacture 1.
Objectives The objectives of this area of the inspection were to verify that:
The fuel rod assembly and quality control practices and a.
procedures are sufficient to give assurance that manu-factured fuel rods meet specifications and contract requirements.
b.
The manufacturer's system is capable of producing quality fuel rods.
2.
Method of Accomplishment The preceding objectives were accomplished by:
Review of the Quality Assurance Manual dated August 5,1977, a.
Sections 5, 10, 11, and 14, which establishes the general.
requirements for fuel rod manufacture controls.
b.
Review of the HTGR Fuel Specifications, GA 10600, Revision W, which establishes the specific requirements for fuel rod manufacture controls.
c.
Review of the following detailed procedures for the evaluation of fuel rod manufacture:
(1) QDI-30-2, Fuel Quality Operating Procedure for Evaluation of Fort St. Vrain Fuel Rods by Electrical Resistance, Revision C,
)\\19 3S\\
5 (2) QDI-30-4, Sampling Plan for Fuel Rods, Revision A, (3) QDI-30-22, Matrix Uniformity and Filler Content (Quinoline), Revision A, (4) QDI-30-25, Determination of Fuel Rod Homogeneity by Gamma Counting with GE (Li) Detector, Revision A, (5) FPD-401, Carbonizing Fuel Rods, Revision D, (6) FFD-403, Final Heat Treat Furnace, Revision G, (7) FPD-410, Final Heat Treat turnace Calibration, Revision C, and (8) FPD-412, Carbonizing Furnace Calibration, Revision C.
d.
Inspection of the heat treat and carbonization furnaces and their controls.
Inspection of the lab equipment e.g. gamia scanner and e.
resistance bridge, used with the above procedures.
f.
Verification of the implementation of the above procedures by review of reports, logs, and other records.
3.
Findings a.
Deviations See Notice of Deviation, Items A and B.
b.
Unresolved Item Fuel Specification GA 10600, in section 5.2.3.2, paragraph 3.2, defines the acceptable electrical resistance as "less than or equal to" X ohms per inch and the unacceptable (Critical Region) also as "less than or equal to" X ohms per inch.
General Atomic (GA) will take the necessary steps to correct this inconsistency.
c.
Comments Material in the form of fired fuel rods was not available for inspection at this time. This ccope will be covered during the next inspection.
